IMPROVEMENT IN DUMPING-PLATFOR MS FOR HARVESTERS.

Gite gtlptule ttftttti! hr in flgrst litters 33mm imt mnliiugpnrt of the52mm To ALL WHOM IT MAY oouonnn:

Be it known that I, DANIEL Ml SWARTZ,.of Lewisburg, in the county ofUnion, and State of Pennsylvania, have invented an improved HarvesterDumping-Platform; and I do hereby declare that the following is a fulland exact description thereof, reference being had to theaccompanyingdrawings, making part of this specification-- i 5 i Figure'lbeing aplan of my improved platform with its connecting parts applied tothe cutterbar of a harvestep. 1

Figure 2, aside elevation thereof.

Figure 3, a transverse vertical section of the platform and cutter-bar.

Like letters designate corresponding parts in all of the figures. i g

The leading feature of my invention is the einployment of asupportng-platform behind the cutter bar, said supp orting-platformhaving an intermittent revolving movement given to its upper surface inthe direction opposite to the motion of the harvester itself, and beingprovided with rake-teeth for the purpose of carrying over the grain anddepositing it in bunches on the ground.

LetA represent the cutter-bar of nt -harvester. Behind this is locatedmy supporting-platform B its position when at rest being inclinedforward, about asrepresented in fig. 2, so that its forward. edge shal tbe .nea'r to and at about the same height as the rear edge of thecutter-bar. It has journals G G centrally at its ends, which havehearings in or on the shoes D E'of the harvester, through the latter ofwhich one extends and projects far enough to receive a pinion, 9, into'wl1ich"gears a cogdvheel, H, by which the movements are given to thesupporting-platform, being communicated by a lever, L, concontricfiviththe cog-wheel, and operated either by hand, by foot, or through suitableconnections automatically by the machinery of the hurvester. In the faceof the cog-'wheel Hisa. set of concentric equidistant holes, 7: 71,connected by a circular groove, '2', into which spin, m, of a pawl, I,enters, and holds 'theplatform successively in the proper position, asshown, after each half revolution. The groovei guides the pawl-pin fromhole to hole It without failure. The lever L l has a catch, 7, whichtakes into the teeth of the cog-wheel II, which thus serves theadditional purpose of a ratchet-wheel. The forward end of thespring-pawl I- turns outward somewhat, as shown infig. 1, so that as thelever is brought back it entcre behind the pawl, and by a wedge actiondraws the pawl-pin from its hole It, leaving the wheel H free to turn.The lever L is then moved forward, thereby causing the platform B torevolve in the opposite direction to that of the motion of theharvester, as relates to itsupper surface, till the pawl-pinmspringsinto the next hole, It, andthe platform has made just half arevolution, placing it in the same positiomas before,'but the other sideup,.both sides being alike. The platform has rake-teeth C C projectingfrom both sides, near or on the central line. These platform-teethproject far enough to give them about the same sweep asthe edges of theplatform. They are either driven into or through the platform, or areinserted into separate strips,r c, which are secured to the platform.This; construction cou templates a. Hat or wide and thin platform,substantially us'showri, though this form is not essential. Thissemi-revolution of theplatform backward, whenever sufficient grain hasaccumulated on it to make a bunch, instantlydraws the grain backwardaway from the cutter-bar, and deposits it evenly on the ground, thefront side of the platform, as it goes upward and backward, finallystriking the butts of the straw and evening them. Then the under sidecoming up into the sam'e position, the platrorm is ready to proceed asbefore. .The inclined position of the platform causes the grain to restsufficiently high over the stubble not to drag off. It should be wideenough not to allow the grain to fall over till the platform turns.While the grain isfalling on the' platform the butts rest onthecuttpr-bar A, audit he position of the forward edge of the platform13 determines the amount of grain that will restthcreon, and the size ofthe gavcls or bundles. By adjusting the platform forward the bundles aremade smaller, and vice versa. The platform is adjusted by having thebearings I) b of its journals adjustable by slots 02 cl and screws (4 a,or equivalent means.

This revolving platform is not to be confounded with, tilting-platformswhich simply let the grain down hehindjthe cutter-bar. My platform rakesthe grain away and over backward from the cutter-bar.

What I claim as my invention, and desire to secure by Letters Patent,is-' A dumping-platform, B, revolving intermittingly backward from themotion of the harvester, and provided with one or more rows. of teeth,(3 C, substantially as and for the purpose herein specified.

I. also claim the cog and ratchet-wheel H, providei with the holes h h,and groove 2', in. eombinotion with thespring-pawl I, andoperating-lever L, snbstantially as and for the purposeherein described.

7 Inlso claim the combination of the revolving platform B, ratchet-wheelH, springspawl I, and lever L, substsntinllf M and for the purposeherein specified.

The above specification vof my improved revolving platform fo'iharvesters signed by me this day of January, 1867;
